Fabspeed Over Axle Link Pipes for 982 Porsche 718 Cayman GT4 RS

By replacing the restrictive factory over axle pipes, one can effectively boost power, shed weight, and infuse a more aggressive GT3 engine tone into the vehicle. Serving as an ideal initial modification and a logical upgrade akin to the regular GT4, Fabspeed’s Over Axles offer a seamless transformation. The design process commenced with 3D scanning the entire exhaust system using the CREAFORM 700 Handscan, enabling the creation of a precise Solidworks 3D model. Subsequently, the exhaust and fixtures were meticulously crafted based on this model to ensure a perfect fit to OEM standards. At Fabspeed USA, the tubing is then mandrel bent in-house on a UNISON limited CNC aerospace electric tube bender, utilizing T304 stainless steel tubing that boasts a 40% increase in size compared to factory specifications, facilitating maximum flow. Additionally, the heat shielding features a stainless steel shell and a ceramic fiber core capable of withstanding continuous temperatures of up to 2400 degrees Fahrenheit, ensuring exceptional insulation effectiveness.


  • The over axle link pipes offered by Fabspeed promise to enhance the robust, throaty tone of your GT4 RS. Experience the remarkable difference in volume and tone, which is both impressive and straightforward to install or remove.


  • In an exhaust system that remains stock with no tune, a significant increase of 30hp at 4750rpm and 34ft/lbs of torque at 4750rpm was achieved. This represents a substantial gain of 33hp at the crankshaft. Additionally, peak horsepower surged from the baseline of 456whp to 474whp, while torque escalated from 330ft/lbs to 341ft/lbs.


  • Choice of a resonated or non-resonated configurations
  • Impressive dyno proven power gains of 30whp and 34ft/lbs
  • Save -12lbs (5.4kg) compared to the stock components

  • Bi-layer heat shielding consisting of a ceramic fiber core and stainless steel shell
  • Heat shielding can handle up to 2400°F (1300°C)

  • All Fabspeed products are expected to ship within one week of order, though timelines are often much quicker
  • After testing with less heat shielding Fabspeed saw no difference in suspension damper temperatures. Thus they may come with less heat-shielding than pictured or use hose clamps instead of welded on heat shielding. this will not affect performance

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
